you can still reach in and turn the lights on the hatch on.
You cant of you have alot of gear in there covering up the switches.
Last night was actually my first try at this. I loaded up the back in anticipation of an upcoming camping trip, than tried accessing stuff through the back window. Couldn't get to the switches due to the gear I had back there, and I had a heck of time trying to get to the headlamp I keep in the wheel well recess.
Sorry, but this is a pretty big fail. Chances are Ill end up trying to find a battery powered stick on LED to put somewhere back there.
